Which article focuses on the identification and use of grounded conductors?

The correct answer is found in Article 200 of the National Electrical Code (NEC), which specifically addresses the requirements for grounded conductors. This article outlines the identification, use, and connection of grounded conductors in electrical systems. Grounded conductors play a critical role in ensuring the safety and efficiency of electrical installations by providing a pathway for fault currents and establishing a reference point for voltage levels.

In Article 200, you will find important provisions regarding the proper marking of grounded conductors, as well as guidelines for their installation, which ensure both compliance with safety standards and effective fault protection. For example, the NEC specifies color coding for grounded conductors, which is essential for preventing misconnections and ensuring proper maintenance.

The other articles mentioned, while relevant to specific aspects of electrical installations, do not center on the identification and use of grounded conductors as comprehensively as Article 200 does. This focus on grounded conductors is essential for upholding electrical safety and integrity in various applications throughout electrical systems.
